一、植物病毒种传的概况许多植物病毒可经种子传播。据不完全统计;种传的植物病毒达119种(包括不同的病毒株系),能种传病毒的植物有162种。病毒种传这一特性在植物病毒的生态体系及病害流行中起重要作用,特别中对那些寄主范围较窄,无越冬(越夏)寄主植物和介体的病毒尤为重要。病毒可随种子的调运而远距离传播。对许多种传病毒来说,种子是其很好的“温床”。在此,病毒可安全的渡过逆境(如越
First, the overview of plant virus germline Many plant viruses can be spread through the seeds. According to incomplete statistics, there are 119 species of plant viruses transmitted (including different strains of viruses), and 162 species of viruses can be transmitted. This feature of virus transmission plays an important role in the plant virus ecosystem and disease epidemic, especially for those viruses that host host plants and mediators that have a narrower range of hosts and no overwintering (over summer) host plants. The virus can be transported with the seeds and long-distance transmission. Seeds are a good “hotbed” for many types of viruses. In this, the virus can safely through the adversity (such as Vietnam
